(01. in-16.5)

This invention relates to a life saving apparatus for submarines, and it is primarily an object ofthe invention to provide an apparatus of this kind to admit in an emergency air within asubmarine when in submergence.- v

It is also an object ofthe invention to provide an apparatus of this kind including a flexible hose line in communication within a submarine together with means carried by the submarine for normally maintaining the hose line in compacted form and wherein means are also provided'for raising the outer end portion of the hose line to the water surface so that the interior of the submarine may be placed in communication with the atmosphere and thus prevent asphyxia of the crew in the event the vessel is incapable of rising to the water surface. I

The invention also has for anobject to provide an apparatus of this kind including a valve struc ture arranged at the outer extremity of the hose line together with buoyant means for raising said valve structure above the water surface, said valve structure when in this position having means to effect the opening of'such structure for the flow of air therethrough and through the hose line to a submarine in submergencer d The invention consists in the details of construction and in the combination and arrange ment of the'several parts of my improved life saving apparatus for a submarine whereby cer-' tain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be'hereinafter more fully set forth;

The novel features of my invention will hereinafter be definitely claimed. a

In order that my invention may be the better understood, I will now proceed to describethe same with reference to the accompanying drawings, wherein:-- l 1 Figure 1 is a somewhat diagrammatic view partly in elevation and partly in section illustrating an apparatus constructedin accordance with an embodiment of my invention; 7

Figure 2 is a fragmentary detailed view partly in section and partly in elevation illustrating the portion of the gearing for driving the reel;

Figure 3 is a view in top plan of the valve structure as herein embodied;

Figure 4' is an enlarged vertical sectional view taken through the valve structure as herein disclosed with certain of the parts in elevation;

Figure 5 is a view in bottom'plan of the structure illustrated in Figure 4 with certain of the parts omitted. f

As disclosedin the accompanying drawings, D denotes the deck of a submarine upon which is rotatably mounted a reel R.. This reel R rotates with a shaft 1 which is rotatablysupported by the bearing standards '2 suitably mounted upon the deck D. Winding upon the reel R is a flexible hose line H, the inner extremity of which being in communication in aconventional manner with a hollow portion of the shaft 1. This hollow portion of the shaft 1 is in communication through a pipe line'3 with the desired pump (not shown) within the submarine and which pump when in operation operates to draw air through thelines H and 3 and discharge the same within the boat.

As any preferred type of pump can be used it is not believed necessary that the same be described and illustrated.

An end portion of the shaft 1 has freely mounted thereon a worm wheel 4, said wheel having a clutch face 5 for coaction in a well known way with the clutch member 6. This clutch member 6 is keyed to the shaft 1 for rotation therewith but free to have movement lengthwise thereof so that the member 6 as desired can be shifted intoor out of clutching engagement with the face 50f the worm wheel 4. Operatively engaged with the-member 6 in a conventional manneris a throw-lever -'Z and this lever 7 is operatively connected through the medium of a rod 8 with an operating member 9 suitably positioned within the vessel. As particularly illustrated in Figure 1 of the accompanying drawings, it-is to be noted that bypulling down on the member 9 the clutch member 6 may be disengaged from the clutch face 50f the worm'wheel 4 and vice versa.

Meshing with the worm wheel 4 is a worm 10 carried by a shaft 11. This shaft 11 extends within the submarine and is in operative connection, as at 12,"with a drive shaft 14. As disclosed'in Figure 1, this drive shaft 14 is comprisedwithin anelectric motor E although it is to be stated that this shaft may be driven in any'desired manner.

The outer extremity of the hose line H constitutes'arigid section 15 of desired length and threadedupon the outer or free end portion thereof is'a valve casing 16 of desired dimensions and configuration. The outer extremity of this rigid portion or section 15 extends a slight distance within the housing or; casing 16 as is Y particularly illustrated in Figure 4. Disposed over this inner or inserted end of the pipe section 15 is a guard ordeflector 1'7 herein disclosed as conoidal'in form with its apex upwardly disposed.

hose line 15, into; the subm t p mp h n iot rei ied to- This guard or deflector '7 is positioned directly below an opening 18 provided in a septum or partition wall or plate 19 intersecting the housing or casing 16, the wall of said opening 18 constituting a seat for a valve member 20. The valve member 20 is carried by theelower end portion of a stem 21 which extends upwardly and is slidably disposed through the top wall 22 of the housing or casing 16. As illustrated in Figure 4 this top wall 22 is comprised within the removable head or capfor the housing or casing 16.

The upper or outer end portion of the stem is flattened, as at 23, and is positioned between the inner lapping portions of a pair ofrock arms 24, said flattened portion 23 and lapping portions of the arms 25. The overlapping portions of the arms 24 are each provided with an elongated slot 26 through which the pin is directed and thus permitting the desired functioning of the parts.

Under normal conditions the hose line H is wound upon the reel R as illustrated in Figure 1,
